Driver’s Visual Attention Analysis in Smart Car with FHUD

This study explores the impact of cues provided by the full windshield head-up display (FHUD) on the visual attention allocation of the driver under different scenes. The full windshield highlights situational cues related to the driving task. In terms of the perception of situational cues, FHUD changed number of fixations and mean fixation durations of drivers. Number of fixations and mean fixation durations in the condition with FHUD were lower than that in the condition without FHUD. In the terms of percentage dwell times in area of interest (AOI), percentage dwell times in front of the field of vision of the driver in the condition with FHUD was larger than that of the control condition, percentage dwell times on both sides was smaller than that of the control condition. It indicated that FHUD could help drivers’ more effectively perceive cues and improve drivers’ visual attention allocation.
